WILLIAM B. MORRIS, OF INDIANAPOLIS, INDIANA, ASSIGNOR OF ONE-HALF TOEMIL DIETZ, OF SAME PLACE.

FOR TRUCKS.

SPECIFICATION forming part of Letters Patent No. 436,986, datedSeptember 23, 1890.

Application filed April 18, 1890. Serial No. 348,511. (No model.)

To all whom it 71mg concern.-

Be it known that 1, WILLIAM B. MORRIS, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Corner-Irons forTrucks or Tables, of which the following is a specification.

The object of my said invention is to produce a joint-iron by which theside and end rails of truck -frames, tables, &c., may be strongly unitedand the posts or legs secured thereto with a minimum cost for materialand labor. 7

This invention will be first fully described, and then pointed out inthe claims.

Referring to the accompanying drawings, which are made a part hereof,and on which similar letters of reference indicate similar parts, Figure1 is aperspective view of a truck, such as is used in factories,warehouses, and such like places, provided with my said invention; Fig.2, a horizontal sectional View of one of said corners, and Fig. 3 afragmentary perspective view of my invention as applied to a table.

In said drawings, the portions marked A represent the side rails of thetruck or table; B, the end rails; O, my improvedjoint-iron, and D theposts or legs.

The rails A and B are in general form similar to the rails of ordinarystructures of this character. Each, however, has a transverse groove,into which a flange on the jointiron 0 enters. For trucks the side railspreferably pass the end rails, as shown in Figs. 1 and 2, while fortables they preferably come The joint-irons C have flanges c,.c and 0One member extends along the side rail and the other along the end rail.The flange c The flange c enters the corresponding groove in the endrail, while the flange c engages with the side of the post or leg D. Fortrucks the same groove which receives the "flange 0 also preferablyreceives the end of the end rail. This is best shown in Fig. 2, whichshows the groove of sufficient width to receive both of these parts.

When the parts are formed as shown and placed together, they are securedby the bolt O, which passes through the rail A and joint-iron O and thepost or leg D. This is the only fastening that is necessary in thisconstruction, no other bolts, screws, or other fastening devices beingrequired in the construction shown for trucks. This results in greateconomy in the manufacture of frames for such purposes, as heretoforeseveral bolts and screws have commonly been required to complete thefastening, adding considerably to the expense. In the table construction(shown in Fig. 3) it is desirable that the side and end rails shall besecured together by nails driven through one into the end of the other,or by screws 0 passing through one member of the joint-iron into thecorresponding member of the frame until at least the top of the table isput in place; but even this is not absolutely necessary, and in any casethe joint-irons receive the strain of the legs or posts.

The posts or legs D are of the ordinary and well-known construction.They are secured against the joint-irons O, resting partly in therecesses, therein which are oppositely bounded by the members of saidjoint-irons, which extend along the end rails and the flanges c and theyare held in position by the bolt C, as above stated. The result is thatthey are held firmly with but little expense for labor or for fasteningdevices.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combinatiomwith the side and end rails and the post or leg of atruck or table, of a joint-iron O, constructed as shown and providedwith the flanges 0, c and c and a bolt, which passes through one of saidrails and said post or leg, and one member of said joint-iron parallelwith the other member of said joint-iron, substantially as shown anddescribed.

2. A joint-iron for securing the side and end rails of a frame and postsor legs thereto I In witness whereof I have hereunto set my 10 together,which consists of two members arhand and seal, at Indianapolis, Indiana,this ranged at right angles with each other and 12th day of April, A. D.1890. having three flanges or projections, two of 5 which enter saidgrooves in the rails, and the WILLIAM B. MORRIS. [L. 3.]

third of which extends out at right angles with one member and parallelwith the other, Witnesses: thereby embracing the post or leg on threeCHESTER BRADFORD, sides, substantially as shown and described. JAMES A.\VALsH.
